89	help
90	  Sometimes, for example if the display is mounted in portrait
91	  mode or even if it's mounted landscape but rotated by 180degree,
92	  we need to rotate our content of the display relative to the
93	  framebuffer, so that user can read the messages which are
94	  printed out. Enable this option to include a text driver which can
95	  support this. The rotation is set by the 'rot' parameter in

104	  needing to provide a bitmap for each font and size that is needed.
105	  With this option you can adjust the text size and use a variety of
106	  fonts. Note that this is noticeably slower than with normal console.

112	help
113	  This sets the font size for the console. The size is measured in
114	  pixels and is the nominal height of a character. Note that fonts
115	  are commonly measured in 'points', being 1/72 inch (about 3.52mm).
116	  However that measurement depends on the size of your display and
117	  there is no standard display density. At present there is not a
118	  method to select the display's physical size, which would allow
119	  U-Boot to calculate the correct font size.

125	 Normally the display is black on a white background, Enable this
126	 option to invert this, i.e. white on a black background. This can be
127	 better in low-light situations or to reduce eye strain in some
128	 cases.

133	  If firmware (whatever loads u-boot) has already put a splash image
134	  on screen, you might want to preserve it until whatever u-boot
135	  loads takes over the screen.  This, for example, can be used to
136	  keep splash image on screen until grub graphical boot menu starts.

142	depends on DM_VIDEO
143	help
144	  This is a work-around for boards which have 'lcd' in their stdout
145	  environment variable, but have moved to use driver model for video.
146	  In this case the console will no-longer work. While it is possible
147	  to update the environment, the breakage may be confusing for users.

558	help
559	  This allows the colour buffer frame buffer driver to support
560	  a limited number of ANSI escape sequences (cursor control,
561	  erase functions and limited graphics rendition control). Normal

589	  the serial port. When this option is enabled, a board-specific
590	  function video_get_info_str() is called to get the string for

645	help
646	  Enables a simple generic display driver which utilizes the
